Improved hydro-motor



'UNITED STATES PATENT OFFICE.

THOMAS WELHAM, OF BROWNSVILLE, NEBRASKA.

IMPROVED HYDRO-MOTOR.

Specilcation forming part of Letters Patent N0. 42,979, dated May 31,1864.

To all whom it may concern:

Beit known that I, THOMAS WELHAM, of Brownsville, county of Nemaha, andTerritory of Nebraska, have invented a new and Improved HydrolnotiveEngine; and I do hereby declare that the following is a full and exactdescription ot' the same, reference being had to the accompanyingdrawings, and to the letters of reference marked thereon, making a partof this specification.

rI he nature of my invention is an elastic cylinder with connections onthe outside of the cylinder to operate the drivin g-shaft also, a' flange with apertures in which the crank-pin is fastened for the purpose ofshortening or lengthening the stroke of the cylinder by shifting theconnecting-rod at any distance from the center to the outside of theflange; alro, the arrangement and combination of a slide and leversoperating as cut-oli's for the elastic feed and discharge pipes workinghorizontally under the main cylinder.

To enable others skilled in the art to make and use my invention, ldescribe its operation and construction as follows:

Figure 1 represents a side elevation; Fig. 2, view of the bottom,showing the pipes and cut offs.

A represents the box or frame which snpports the operating devices ofthe engine.

B is the elastic cylinder, made of india-rubber or other elasticsubstance or material, surrounded and strengthened by a coil of wireplaced on the outside, or manufactured in the cylinder. 1

C is the connectingrod attached to the outside of cylinder B, and alsoto the crank-pin D of the flange E. This il-ngeE is a circular plate,and has two or more holes, F, for the purpose of shifting the crank-pinD nearer to or farther from the center of the flange E, so as tolengthen or shorten the stroke of the cylinder B, according to thepressure and supply of water and power required.

G G represent elastic pipes underneath, which act as feed and dischargepipes, so that as the flow of water is let into either pipe G it passesthrough that pipe up into the cylinder B, and is again discharged fromthe cylinder through the other corresponding pipe, G, and as the Waterenters one pipe G it is cut oit1 by the horizontal lever H at the otherend of the other pipe G, as lettered G* G*. The levers H being moved tothe right` or left by the center horizontal slide, J, (which hasdiagonally-shaped slots K at each end, in which rollers L revolve onpins at the end ot' each lever H operate alternately. The levers workingon screws or pivots M at their opposite ends, and as the levers H moveto either side, o ne lever presses against one of the elastic pipes G,at the point Gi, closes it, and cuts oli' the flow ot1 water, While theopposite lever H recedes from the opposite pipe G, at the point G", anditis opened for the water to continue its flow, thus alternately openingand shutting the pipes G, at the point Git. The center slide, J, movesbackward and forward between four siderollers, N, and is operated by theaction ot' the cylinder B by being connected with the cylinder B orshaft D, as I deem most convenient or effective.

P is a fly-Wheel attached` to the one end ot' the main driving-shaft lt,and the ilange E is located on the other end.

What l claim as my invention, and desire to secure by Letters Patent, is

1. The elastic cylinder B and its outside connection, in combinationwith the drivingshaft at the ange E by a connecting-rod, O, asdescribed.

2. The ange E, with its apertures F, in combination with theconnecting-rod O, and the elastic cylinder B.

3. The construction of the slide J and levers H, when arranged andcombined as cut-offs, as herein described.

V 4. The construction, arrangement, and combination of the elasticcylinder B, with its elastic feed and discharge pipes G and theircutofts H, when constructed, arranged, and combined as herein described.

THOS. WELHAM.
